RimWorld is a landmark sci-fi colony simulation from Canadian developer Tynan Sylvester — a game that describes itself not as a challenge to win, but as a story generator driven by an intelligent AI Storyteller. Three survivors crash-land on a distant frontier world at the rim of known space and must build a colony to survive. What unfolds is not scripted — it emerges from the interaction of deeply simulated psychology, ecology, gunplay, medicine, relationships, art, trade and weather systems. Choose your AI Storyteller: Cassandra Classic for rising tension, Phoebe Chillax for a gentler pace, or Randy Random for pure chaos.

Key Features: • AI Storyteller — three storyteller modes that generate unique emergent stories, not scripted events • Deep colonist simulation — psychology, relationships, addictions, moods and mental breaks • 5 DLC expansions — Royalty, Ideology, Biotech, Anomaly, Odyssey (July 2025) • Massive modding community — thousands of Steam Workshop mods from QoL to full overhauls • DRM-free — purchase directly from Ludeon with no DRM restrictions
